I've been using this system for a Private NAS and some simple server applications. Based on Debian Linux (Open Media Vault). The system is powerful, in any point too weak, apart possibly from the 250GB hard drive. The N40L has enough USB ports on the front and back, as well as a USB port directly on the motherboard for boot systems via USB. It has 4 HDD bays which are very easy to handle and offers opportunities to a CD / DVD / BR drive to integrate etc.. The volume is ok, apart from the power supply fan of the basis of its size but audible noise is of itself, I personally have this replaced by a somewhat higher quality and you can no longer imagine on the basis of whether the customs N40L is on or off.
Total points - 4
Hardware - 4 Housing and construction - 5 Noise - 4 Good value - 5
